Cairo is the capital and largest city of Egypt. The Cairo metropolitan area, with a population of 21.3 million, is the largest metropolitan area in the Arab world, the second largest in Africa, and the sixth largest in the world. Cairo is associated with ancient Egypt, as the famous Giza pyramid complex and the ancient city of Memphis are located in its geographical area. Located near the Nile Delta, Cairo was founded in 969 AD during the Fatimid dynasty, but the land composing the present-day city was the site of Ancient National Capitals whose remnants remain visible in parts of Old Cairo. Cairo has long been a centre of the region's political and cultural life, and is titled "the city of a thousand minarets" for its preponderance of Islamic architecture. Cairo is considered a World City with a "Beta +" classification according to GaWC.
